SPECIFICATION forming part of Letters Patent No. 263,455, dated August29, 1882,

Application filed August 26, 1881. (No model.)

To all whom it may concern:

Be it known that I, CHARLES H. AMIDON, of the city ofBuffalo, in thecounty of Erie and State of New York, have invented new and usefulImprovements in Bit-Braces, of which the following is a specification.

This invention relates to a novel construction of the head and socketportions of a bitbrace, whereby the brace is materially cheapened andsimplified.

The invention consists of a head of peculiar construction, which isapplied to the brace bar or rod before the latter is bent, whereby thehead is securely held in position on the bar 5 also, of a socket-securedto the brace-rod by impressing the metal of the socket into depressionsor indentations formed in the rod, and of the particular construction ofthis socket, as hereinafter fully set forth.

In the accompanying drawings Figure 1 is a side elevation of my improvedbrace. Fig. 2 is a sectional elevation, on an enlarged scale, of thehead of the brace. Fig. 3 is a sectional elevation of the socket appliedto the end of the brace-rod previous to securing the parts together.Fig. A is asimilar view, showing the parts secured together. Fig. 5 isan elevation of the end of the brace-rod to which the socket is applied.Fig. 6 is a side elevation of the socket previous to securing it to therod.

Like letters of reference refer to like parts in the several figures.

A represents the rod or bar of the brace, and B the head, constructed ofwood and atiached to one end of the rod A. The latter is provided at itsend with a collar or annular enlargement, a. The inner portion of thehead B is constructed with a bore, 1), which fits around the rod A, andthe outer portion of the head is constructed with a larger bore, 11,which fits over the enlargement a of the rod. A shoulder, b formed atthe junction of the bores 11 and b, fits against the inner side of theenlargement a and prevents the head from being separated from the rod.The head is slipped on the rod before the lat ter is bent, and issecured in place on the rod by a wooden plug, 0, which fills the outerportion of the bore I) above the enlargement to, and which is glued orotherwise secured in the bore I). The head 13 is by this means firmlyheld on the rod A against movement lengthwise of the rod, but permittedto turn thereon.

D represents the socket, which receives the end of the bit, and which issecured to the opposite end of the rod A. The latter is constructed withone or more notches or depression s, 6, near its end, which notches arecovered by the sleevefat the inner end of the socket.

grepresents one or more enlargements or protuberances formed on thesleeve f of the socket, in line with the notches e of the rod; and h isa shoulder formed in the bore of the sleeve f, and bearing against theend of the rod A when the sleeve is in the proper posi= tion on the rod.

The socket D is constructed of malleable iron or similar malleablemetal, and secured to the rod by applying the sleeve to the end of therod, with its enlargements g opposite the notches e of the rod. Thesooketis then placed in a powerful press, whereby the metal of thesocket is depressed into the notches e of the rod, thereby securelyfastening the socket on the rod. The pressure of the press falls uponthe enlargements g, and the latter are made just large enough to replacethe metal which is forced into the notches 6, thereby leaving theexterior surface of socket of a smooth cylindrical form when the partsare secured together, as shown in Fig. 4. It is obvious, however, thatthe metal of the socket can be pressed into the notches e of the rod Ain the absence of the enlargements g of the socket; but this would formindentations in the outer surface of the socket, and I therefore preferto employ the above-mentioned enlargements.

I claim as my invention-= 1. The combination, with the brace-rod A, madeof uniform thickness throughout its length, except at its end, where itis provided with an enlargement or collar, a, of the head B, constructedwith an inner narrow bore, 1), fitting on the rod, and an outer enlargedbore, b, fitting over the collar a, the head being slipped on the rodbefore it is bent and held on the same by a plug, 0, secured to the boreinto the notches e is replaced by the enlargeb, and bearing against thecollar a, substanments 9 and a smooth exterior form of the 10 tially asset forth. socket preserved, substantially as set forth.
